BED-SPRING.

Specification of Letters Patent.

.Application filed March 13, 1905i SerialNm 249|783.

useful Improvements in Bed-Springs, of-

which the following is a specification, such as will enablethose skilled in the art to which it appertains to make and use the same.

This invention relates to bed-springs and bed-spring frames; and the object thereof is to provide a bed-spring of the fabric type with improved end connections which facilitate the connection of the bed-spring with an ordinary bed-s ring frame composed either of wood or ang e-iron.

The invention is fully disclosed in the following specification, of whi ch the accompanying drawings form a part, in which the separate parts of my improvement are designated by suitable reference characters in each of the views, and in which- Figure -l is a plan view of a bed-spring frame, a bed-spring secured thereto according to my invention, the frame being made of wood; Fig. 2, a section on the line 2 2 of Fig, 1; Fig. 3, a view similar to Fig. 2, but showing a frame made of angle-iron; and Fig. 4, a section on the line 4 4 of Fig. 3.

In the drawings forming part of this specification, reference being made to Figs. l and 2, I have shown a bed-spring frame comprising parallel side bars a and parallel end bars b, the end bars b being preferably wider in cross* section than the side bars andbeing placed on and bolted to the side bars, as shown at b2, and in said figures of the drawings I have also shown at c a fabric bed-spring on which the mattress and bedclothing are placed in the usual manner.

In the practice of my invention the op oattened out in a press or in any desired manner, as shown at c2 in Fig. 2, and the iiattened end portions are secured in transversely-arranged clips or binders d, which in the construction shown are countersunk in the top surface of the`end bars l) of the bed-spring frame, as clearly shown in said figure, and secured in position by nails d2 or in any other desired manner.

The transversely-arranged clips or binders d, which are secured to the opposite ends of the bed-spring c, are composed of oblong strips of sheet metal folded centrally to form bottomand top portions al3 and d4, which are secured together and secured to the ends of the bed-spring by rivets d5. The bottom part of the end clips or binders d are provided with longitudinal depressed portions d, which range longitudinally of the end bars l) of the bed-spring frame and transversely of said frame and which form corresponding grooves (Z7, and in practice the fiattened-out end portion c2 of the bed-spring is formed into coils c3, which are placed in said grooves, and the rivets d5 are placed between said coils and grooves and the inner edges of the clips or binders d, and this construction enables the rivets to securelyhold the ends of the bedspring and prevent Athe latter from drawing out, and the nails d2 bind the top and bottom parts of the end clips or binders d together on the outer side of the grooves 7 and coils c3. It will therefore be seen that the end clips or binders c securely bind and hold the ends of the bed-spring and prevent the latter from drawing out and prevent the coils of the spring from unwinding, and at the same time said clips or binders afford asirnple and eiective means for securing the spring to the ends of the spring-frame.

Although I have shown and described the end clips or binders d as countersunk in the end bars of the frame, it will be apparent that this is not absolutely necessary, and said end clips or binders may be placed on the'end bars b of the frame and may be nailed or otherwise secured thereto.

In Figs. 3 and 4 I have shown my improvement applied for securing a fabric bed-spring to a frame composed of angle-iron, and in this construction the frame comprises parallel side bars e, of angle-iron, and transverse end bars f, secured thereon, and the end bars f are provided at their outer edges with up right members f 2, and the end clips or binders d in this'form of construction are made a little wider and rovided at their outer edges with downward y-directed flanges g, the folded portion of the sheet of metal from which said clips or binders are formed being bent downwardly to form the depending anges g, and said folded portion is also provided in the fold thereof with a rod g2, which gives strength thereto, and the upwardly-directed parts f 2 of the end bars f are provided at intervals with slots or openings f3, and the depending anges or parts g of the clips or binders d are provided with holes f 4, and rivets or bolts g3 IOO IIO

are passed through these holes and through the slots or openings f3, and instead of e1n ploying the slots or openings f3 ordinary holes may be substituted similar to the holes f4, the object in employing the slots or openings being to be able to cause the holes f4 in the parts g to register more easily with the corresponding holes in the part f2.

In both forms of construction the end clips or binders d are composed of folded sheets of metal, the under side portion being provided with the longitudinal groove all, designed Yto receive'corresponding coils or rolls formed at the ends of the bed-springz I/Vhen the bed-spring is secured to the end clips or binders in themanner described, it will be securely held and will not work loose nor become detached in use, and a bed-spring of the class described provided with end clips or binders, as herein shown and described,

may be easily and conveniently secured to a frame composed either of wood or metal, and changes in and modifications ofthe construction herein described may be made without departing from the spirit of my invention or sacrificing its advantages.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

A bed-spring provided with end clips or binders composed of sheet metal folded longitudinally and centrally to form top and bottom members between which the ends of the bed-spring are secured, the bottom members of said clips or binders being bent downwardly to form grooves, and the ends of the bed-spring being compressed and formed into rolls which are placed in said grooves, and the top and bottom members of said rclips or bind ers being secured together at the opposite sides of said grooves, and the outer edges or folded portions of the clips or binders being bent downwardly to form depending flanges having bolt-holes formed therein, substantially as shown and described.

In testimony that I claim the foregoing as myinvention I have signed myname, in presence of the subscribing witnesses, this 10th day of March, 1905.
